20 Claims.

'I'his invention relates to certain new and useful improvements inlocks, and has as a general object to provide a simple locking devicefor compartment doors and especially 'the doors of in- 5 strument boardcompartments in automobiles.

Another object of this invention is to provide a simple latch lock forcompartment doors of the character described, having a spring latchnormally retractable by a handle knob wherein the l driving connectionbetween the operating knob or handle and the latch is controlled by akey operated lock cylinder by which it may be readily disconnected torender the knob ineffective for releasing the latch.

A further object of this invention is to provide a latch lock of thecharacterdescribed in which the component parts are so formed andrelated to each other that assembly oi the entire mechanism is effectedwithout the use o! screws or bolts and nuts.

Another object of this invention resides in the provision oi a lockdevice of the character described in which the parts are retained intheir assembled positions by the lock cylinder.

And a further object of this invention is to provide a lock device ofthe character described which is so constructed as to permit its use asa non-locking latch to be converted into a locking latch merelyv byproviding a lock cylinder and inserting the same in the handle.

With the above and other objects in view which will appear as thedescription proceeds, my invention resides in the novel construction,combination and arrangement of parts substantially as hereinafterdescribed and more particularly dened by the appended claims, it beingunderstood that such changes in the precise embodiment of the hereindisclosed invention may be made as come within the scope of the claims.

In the accompanying drawings, I have illustrated one complete example ofthe physical embodiment of my invention constructed according to the.best mode Irhave so iar devised for vthe practical application of theprinciples thereof, and in which: i

Figure 1 is a section view through a compartment door equipped with thelock o! this invention; v Figure 2 is a rear view taken on the inside 50of the door and illustrating the latch in its operatlve position;

Figure 3 is a view similar to Figure 2, but with thehandle knobdisconnected from the latch and illustrating the connecting means turnedby the handle without effecting the position oi' the latch; and

Figure 4 is a perspective view oi the various elements of the lockdisassembled and in their proper order o! assembly.

Referring now more particularly ci to the accompanying drawings in whichlike numerals indicate like parts throughout the several views, thenumeral 5 designates a stationary panel, as for instance, the instrumentboard of an automobile, having a door opening 6 adapted to be closed bya door 'Z hingedly mounted as at 8. The opening 6 is provided with aninturned ange 9 alongits edge opposite the hinged connection 8 withwhich the active end 10 of a latch bar 11 engages to hold the door 'Iclosed.

The latch bar 11 is formed from a blank of sheet metal-and comprises aatcentral portion 12 .having a round opening 13, whereby the latch baris rotatably mounted on the outer end portion of a drawn hub 14 formedin the door 7. At the opposite ends of the latch bar are oiset feet 15and 16 which serve to space the medial flat portion 12 from the adjacentinner face of the door 7 and position the medial portion of the latchbar with its outer face substantially ilush with the end of the drawnhub 14.

In the space between the latch bar and the door 7, a torsion spring 17is coiled about the hub. One end 18 oi the spring is hooked into anopening in the door 7 and its other end 19 is hooked in a hole 20 in thelatch bar. In assembling the latch bar with the spring and the hub,thespring is placed in tension so that it tends to turn the latch bar aboutthe axis of the hub to engage its operative end portion 10 withtheilange 9. Such rotation of the latch bar is limited by the engagement ofan inwardly directed lug 21 on the latch bar with a lug 22 projectingfrom the end of the hub.

It is observed that the active end l0 of the latch bar is formed by acontinuation of the metal forming the foot 15 and that this end 10 has acam edge 23 arranged to strike the edge of the opening 6 as the door isclosed so as to cam the latch bar past the edge of the opening. It isalso noted that the connecting web 23 of the active latch bar end 10,which engages the ange 9 when the door is closed, is slightly inclinedso that as the latch bar returns to its operative position after thedoor has been closed, it will draw the door firmly against rubberbumpers 24.

Mounted within the hub 14 is a handle knob 25. The handle knob 25comprises a tubular cylindrical portion 26 which is journalled in thehub, and a handle 27 which, in the present instance, is an enlargedknob. The juncture between the tubular cylinder 26 and the knob 2'?affords a shoulder 28 which is spaced outwardly of the iront face of thedoor '7 when the inner end of the cylindrical portion 26 is flush withthe end of the hub 14, and this space is maintained by a ilangedescutcheon plate 29 abutting the shoulder 28. 'I'he escutcheon plate 29is suillciently large to cover the projecting spring end 18.

v Extending from the inner endo! the cylindrical arranged to hold thelatch bar in the plane of its movement 'to and from operative positionengaged over the edge of the opening.
